Just wondering if anyone has used some of the other brands of ESP32 + LoRa
radios, and whether they’d work? There’s a few choices on Amazon. Sparkfun
doesn’t seem to have any with esp32 anymore and choosing their board would
mean porting disaster radio to ARM & how their board is set up.
I ordered lilygo ttgo boards from Aliexpress, but after waiting over 6
weeks, little cameras arrived — the wrong thing. Not willing to roll the
dice again with such a long shipping process.
Seedstudio got in touch, they would give us some free dev boards if
anyone fancied porting disaster radio to their Cortex M4? I don't know
much about them. Would they be more power efficent than the ESP32?
Let me know if you'd like to attempt the port.
Thank you for your reply and interested in lora.
I'm really impressed and fascinated by your project ''Disaster Radio
- LoRa Mesh'' posted on Hackday and i also saw the video you posted
on youtube, it has important implications for our human society.
Actually, the new LoRa-E5 (STM32WLE5JC) series is completely
different from what's on the market. It's much more powerful and with
a low-cost, ultra-low power, extremely compact, and high-performance
LoRaWAN module and also development boards. Link here:
The requires for Sample Test :
1) COULD YOU PLEASE TELL ME WHICH DEVICES OF LORA E5 YOU WILL CHOOSE
AND WHAT KIND OF PROJECTS YOU WILL USE THEM IN? (The project would be
better explained in detail, which is also convenient for us to reach
an early cooperation. Thank you for your time :)
2) When the project is finished, will you posted on hackday or ther
platform and if possible i wanna know how long will it take you to
finish this project?
After the project is delivered, our official Twitter and Facebook
will also promote your project and forward it, bringing more value and
possibility to it.
Since we announced the module, there are a lot positive feedbacks
from the community, and I believe LoRa E5 series will help a lot to
your audience who are interested in long range communication projects.
We are very honored to meet such creative and influential people as
you to cooperate!
Look forward to hearing from you soon and have a nice day. :)

Ages ago I signed up for the open-source program with Lilygo. They
send $1 for hardware purchased through their links.
I used a bit of it to buy and test the parts on the enclosure list.
They just sent me a further $70 generated from DR links and I don't
have any immediate Disaster Radio plans for it.
So if you live in the global South (arbitrarily defined as a
'Developing Country' in green on this
map:https://upload.wikimedia.org/wikipedia/commons/5/54/IMF_Developing_Coun…) and you'd like some TTGO dev boards or enclosure/solar bits then send me an email off-list and I'll get some posted to
If it remains unspent I'll use it to build out a DR network local to
me, but I'm a bit busy for that right now.
